I actually did this with raidou's counter hit combo challenge and I did an electric combo and I was like no way it does that much damage, I tested it in practice and I thought it was a glitch or something, Now watching this video turns out it is. xD
Just do a combo challenge that starts with a counter hit (Honoka has 2 and Raidou I think has one) and don't do what it's telling you to. Every hit will be 125% rather than going down to 40%
